BEAM Robots–little insects made of recycled electronics

One of these days I will build a swarm of these to crawl all over my apartment and tease the cat. They’re self-sufficient, powered by a solar cell, and do nothing but run around looking for more light and avoiding shadows. I suppose in Finland they might end up hibernating under closets in winter, or perhaps attacking you en masse when you return home and turn on the light. Here’s where you can buy kits, if you’re not feeling all hardcore.
